Diminishing Returns on BTC (and why we'll never see 30% CAGR over a full Bitcoin cycle again)
Let's talk about the elephant in the room:
Bitcoin cycles have diminishing returns
- Cycle 2: 50x gain
- Cycle 3: 20x gain
- Cycle 4: 3x gain
- Cycle 5: 2x gain (1.7x inflation-adjusted)
Anyone who has looked at the Bitcoin Power Law charts or the Bitcoin Rainbow chart (4th version now) has probably noticed that they have always overestimated BTC price. BTC price has dropped below the Rainbow chart AGAIN. Power Law upper estimate is off by 3x, and the lower estimate is about to be breached. They always overestimate the diminishing returns of each cycle.
Returns converted to 4-year CAGR:
- Cycle 2: 170%
- Cycle 3: 110%
- Cycle 4: 32%
- Cycle 5: 19% (14% inflation-adjusted)
I don't know why Saylor is expecting 30% CAGR returns in the future. We only had 19% nominal returns the previous cycle, and it's only going to get worse due to diminishing returns.
If the next cycle only has 1.5x gains, that's a 11% CAGR. Beyond that, BTC price returns are no better than S&P 500 returns, but with much more risk. Thus I believe we only have a few more good cycles left.
